Question

we can create our action button on a slide​

Answer 1

Explanation:

Use an Action button to do an action in your presentation, such as going to the next or a specific slide, running an app, or playing a video clip. There are two basic steps for setting up an Action button:

First, you pick an action button from the Shapes gallery

Then you assign an action that occurs when (during Slide Show) you click the shape or point the mouse at it.

The idea is that when you deliver your presentation, you can click or point at an action button to:

Go to the next slide, the previous slide, the first slide, the last slide, the most recent slide viewed, a specific slide number, a different PowerPoint presentation, or a Web page.

Run a program

Run a macro  

Play an audio clip

Put an action button on your slide

Some examples of built-in action button shapes in the Shapes gallery include right and left arrows (commonly understood symbols for going to next, previous, first, and last slides), for playing videos or sound bites, and more.
